3. INSPECT SPEEDOMETER VOLTAGE
(a) While driving the vehicle at the speed of 10 km/h, check
the voltage between the terminals 16 and 1 of the com-
bination meter assy.
STANDARD: Fluctuation between 10 to 14 V or less is
repeated 7 times within 1 sec.
4. INSPECT VEHICLE SPEED SENSOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
1 and negative (-) lead to terminal 2.
(b) Connect the positive (+) lead from the tester to terminal
3 and the negative (-) lead to terminal 2.
(c) Rotate the shaft.
(d) Check that there is voltage change from approx. 0V to 11
V or more between terminals 2 and 3.
HINT:
The voltage change should be performed 4 times for every rev-
olution is not as specified, replace the sensor.
5. INSPECT TACHOMETER / ON-VEHICLE
(a) Connect a tune-up test tachometer, and start the engine.
(b) Compare the tester and tachometer indications.

ADJUST HEADLIGHT AIM ONLY
(a) Place the vehicle in the following conditions.

The area around the headlight is not deformed.

The vehicle is parked on a level surface.

Tire inflation pressure is the specified value.

A driver is in the driver's seat and the vehicle is in a state ready for driving (with a tank full).

The vehicle has been bounced several times.
(b) Check the headlight aiming.
(1) Prepare a thick white paper.
(2) Stand the paper perpendicular to the ground at the position 9.84 ft away from the headlights.
(3) Ensure that the center line of the vehicle and the paper face forms a 90-degree angle as shown
in the illustration.
(4) Draw a horizontal line (H line) on the paper, showing where the headlights should strike.
(5) Draw a vertical line (V line) to where the center line of the vehicle is to be.
(6) Draw 2 vertical lines (by connecting the low and high beam center marks) to where the both head-
lights should strike (V RH and V LH lines).
(7) Draw a horizontal line (by connecting the both low beam center marks) to where the headlights
should strike (H RH and H LH lines).
HINT:
The H RH and H LH line is 0.4° below the horizontal line (H line) of the light axis.
(8) Start the engine.
(9) Turn the headlights ON.
(10) Check that the headlights properly strike the position shown in the illustration.
(11) If not, adjust the lights in the vertical direction.
HINT:
As shown in the illustration, adjust each aim of the RH and LH lights.
(c) When adjusting it in the vertical direction:
Using adjusting bolt A, adjust the headlight aim to within the specified range.
